How to Meet and Exceed Air-Sealing Requirements
Sponsored by:
Learn about code requirements and best practices for air-sealing, air-barriers, and insulation to help reduce home energy consumption.
The 2021 International Residential Code has several provisions aimed at curbing energy consumption in homes. It’s imperative to educate those in the field on both the code and industry best practices, using the right products in the right way to achieve a project’s performance goals.
To help builders and remodelers, we’ll give a condensed view of the air-barrier, air-sealing, and insulation installation details outlined in Table N1102.4.1.1. The requirements there address insulating rim joists so that insulation is in permanent contact with the exterior rim board, that shaft and penetrations to the exterior are air-sealed and insulated, and that narrow cavities be filled with insulation—among other important details. In addition to the code itself, we’ve included articles that demonstrate and explain how to accomplish these commonly required air-sealing and insulation details.
